i IMPROVEMENT IN HARROWS.

The Schedule referred to in these Letters'Patent and making pan of the same.

To all whom it may concern Be it known that I, THOMAS B. COLLINS, of Noank, in the county of New London, and State of Connecticut, have invented a new and useful Improvement will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawing, forming part of this specification, in which Figure 1- is avertical longitudinal section ofmy improved harrow, taken through the line aa x, fig. 2, and showing, in red lines, one part of the harrow turned up for transportation.

Figure 2 is a top view of the same. Similar letters of reference indicate corresponding parts. I

'My invention has for its object to furnish an improved harrow, simple in construction, strong, and dn rable, which will adjust itself to irregularities of the surface of the ground, and which may be conveniently adjusted for transportation, without its being necessary to load it upon a wagon or other vehicle, for that purpose; and V i It consists in the construction and combination of the various parts of the barrow, as hereinafter more fully described.

A is the forwardpart of the barrow, which is made attaching a longitudinal bar, a, and inclined side-bars, a, to a metallic ring-plate, c

The ring-plate c is formed with ears, or lugs, upon its rear edge, upon each side of the rear end of the longitudinal bar a, as shown in fig. 2.

B are the side parts, which are made diamond-shaped in their general form, and are formed by attaching inclined bars I) to the longitudinal metallic bars 7) The bars I) are formed with ears upon one or both ends, to receive the long bolts, or rods, by means-of which the said parts 13 are hinged to each other,0rto the forward part A.

One or more of the parts 13 may be side ofthe harrow, as i'nay be desired.

C are the barrow-teeth, which are secured to the bars a a b, by nuts screwing upon their upper ends, as shown in 1 and 2.

This construction makes the barrow flexible, so that it can adjust itself. to theirregul'ar surface of the ground being harrowed. It also enables the parts B to be folded, or turned up over the part A, as shown in red in fig. 1, for convenience in transportation.

1) are the wheels, the axles E of which are formed upon sockets, so formed as to fit upon the outer ends 'of the rear or longer bars c of the forward part A,

used upon each as shown in fig. 2.

The wheels D are only to be-used when transporting the harrow from place to place, and are to-be detached, when the harrow is to be used for cultivating the ground.

The draught is attached to the ring G, which is see cured to the bar a, in the rear of its forward end, by an eye-bolt, so that the draught may be applied to the rear of the forward end of the harrow, causing the harrow to draw level upon the ground, instead of having its forward entLlift up, as is the tendency when the draught is attached to the forward end of the harrow, in the ordinary manner. e

H is a lever, to the forward end of which is attached a hook, it, which hooks into a staple, or eye-bolt, attached to the longitudinal bar (0, a littlc'in front of its rear end. I

The lever H may also be connected with the rear end-0f the said bar a, by a link, h", pivoted-to the under side of the said lever, and catching7upon a bolthea d,' or other catch, attached to the rear end of the 7 said bar a.

The connection between the lever H and the part A of the barrow is strengthened by the jointed bracerods h the rear ends of which are pivoted to the sides of the said lever B, and the forward ends of which are pivoted to the bars a, of the part A, asshown in figs.

land 2. f

To each side of the lever H is attached a bracket, I,

between the lower ends or angles of which is pivoted the wheel, or wheels J, which, in connection with the wheels D, support the harrow while being transported from place to place.. v

The rear end of the lever H extends back into such more diamoi'id-shaped partsB to the diamond-shaped central or forward part A, said parts being constructed, connected, and operating substantial 1y as herein shown and described, and for the purpose set forth.

2. The combination of the lever H and wheel, or wheels, J, with the forward or central part A of the barrow, substantially as herein shown and described, andfor the purpose set forth. I

3. The combination of the. detachable wheels and axles D E with the forward or central part A. of the barrow, substantially in the manner herein shown and described, and for the purpose setforth.
